KR930008591A - Horizontal and vertical display method and device by hardware - Google Patents

Abstract

The present invention relates to the field of computer graphics control and all fields controlling the screen, and selects the horizontal / vertical writing on the screen to write horizontally while writing 8-bit × 8-bit English vertically, 16-bit × 16-bit Korean, English, Chinese characters. The technical task is to perform vertical writing of special characters.

Therefore, the present invention has a horizontal / vertical writing selector to implement vertical writing, receives a counter value from this register, creates a row address and an open dress, and then selects a data in the character generator by selecting data in the refresh memory suitable for vertical writing. The main point is to print on the screen.

In addition, the present invention is to give a vertical writing to the hardware can be used for vertical writing using the software for horizontal writing, it is intended to be used in novel and newspaper magazine editing, vertical writing document editing.

Description

Horizontal and vertical display method and device by hardware

Since this is an open matter, no full text was included.

2 is a block diagram of a horizontal / vertical display of the present invention;

3 is a detailed circuit diagram of a horizontal / vertical display of the present invention;

4 is a signal flow diagram for a horizontal / vertical display of the present invention.

Claims (3)

In the horizontal writing selection state, the display controller sends the address to the address converter to perform the horizontal writing display through the refresh memory and the character generator.In the vertical writing selection state, the English lines and column counts generate English lines and open dresses. In Korean, English mixed vertical writing, Korean, English mixed rows and column counts generate Korean, English mixed rows and open dresses. The vertical display is performed by applying the address to the address converter and refresh memory and a character generator. Horizontal / vertical display method by hardware. A horizontal and vertical writing selector 10 which can select and use horizontal writing and vertical writing, and an attenuation row counter that counts rows while receiving a row counter value from the horizontal and vertical writing selection unit 10 and decreasing them by one. ), An incremental column counter 40 that counts columns while increasing the value from 0 to 1 when the value of the attenuation row counter 20 reaches "0", and the row count and the column count value are row address 30. And an address converter 60 for converting addresses through the open dress 50, a refresh memory 70 for selecting data memorized by an address from the address converter 60, and the refresh memory 70. A character generator 80 which selects and outputs a character to the display 90 by the data selected by the controller; and data programmed according to an operation signal from the horizontal and vertical writing selection unit 10; An address latch outputting the input / output connection device 100 output to the 110 and the address from the display controller 110 to the address converter 60 by latching the address from the horizontal and vertical write selector 10 according to an operation signal. The division 120 and the division clock 130 for dividing the English clock of the sequence 150 and opening the output to the lowest row of the dress 50, and the horizontal writing of the English clock of the two division counter 130 Display device according to the hardware characterized in that it consists of a multiplexer (140) which is selected by the selection signal of the selection unit (10) and output to the row counter (20). The set terminal of the multiplexer 140 according to claim 2, wherein the horizontal and vertical writing selector 10 stores data stored in the mode register 160 in the horizontal / vertical register 220 and the multiplexer 140 through the multiplexer 170. And outputting the data through the input / output device 10 to the horizontal / vertical register 220 to be input to the incremental column counter 40 through the NOA gate. Horizontal / vertical display device by hardware. ※ Note: The disclosure is based on the initial application.
